Specifically, each of the plurality of cutters 311 may be fixedly mounted on the second rotating shaft 333, and the second rotating shaft 333 may be rotatably mounted on the corresponding connecting arm 331. It can be understood that the plurality of cutting knives 311 are arranged at intervals, and the distance between two adjacent cutting knives 311 can be set according to the required width of the sub-tape 700 a.

As shown in fig. 3 and 6, in some embodiments, the second cutter set 310b may also include one, two, three, four, etc. cutters 311. When the second cutter group 310b includes one cutter 311, the position of the cutter 311 in the axial direction of the second rotary shaft 333 may be set as desired. When the second cutter group 310b includes a plurality of cutters 311, a gap between two adjacent cutters 311 may be different from a gap between two adjacent cutters 311 in the first cutter group 310 a. That is, the vertical projections of the cutter 311 in the first cutter group 310a and the cutter 311 in the second cutter group 310b on the support roller 320 may be offset along the axis of the support roller 320. Accordingly, when the optical film tape 700 is cut by the first cutter group 310a and the second cutter group 310b, the sub-tape 700a having different widths can be obtained. Correspondingly, when the sub-material belt 700a with different widths needs to be cut, the required cutter set 310 can be switched directly by rotating the cutter holder 330 without disassembling and assembling the cutter 311, so that automatic cutter changing can be realized, the cutter changing efficiency is improved, the production efficiency can be improved, and the workload of workers is reduced. In other embodiments, when the cutter group 310 is provided with one group, the sub-tape 700a with different widths can be cut by adjusting the spacing between the plurality of cutters 311.
